  • Control of bias voltage
    Patent number: 7078967
    Abstract: The invention concerns a method for maintaining an optimal operating point of an LDMOS device stable, said LDMOS device producing an output signal including an error signal component. The method comprises separating said error signal component from the output signal of said LDMOS device and using said error signal component for controlling the gate-to-source bias voltage, or Vgs, of said LDMOS device to maintain the optimal operating point of the LDMOS device stable.
